The output voltage is AC? Does this mean that it won't work with DC? A mechanical relay would. Are solid state relays that much different?

Will not work with DC...I learned the hard way with this specific product...Solid state relays involve no moving parts that won't "wear" out or have an annoying click sound. I bought one of these for a electric heater and didn't work...had to go to a different relay...

Correct. The relay is actually turned OFF ONLY at the zero cross point of the AC wave. It can be turned ON at any point in the wave depending on your needs, load, EMI requirements etc. So with DC it would turn on but not off (no matter what your control input) unless the DC voltage dropped to zero for whatever reason. Also It would likely NOT handle anything like the rated voltages(give as RMS) with DC load.

I don't understand your circuit. If you dim the incoming AC voltage the dc output drops off exponentially after 110 Volts. For a better answer Google search the data sheet for this power supply. It's very informative. Good luck with your work.

Hi Frank, my husband Jerry purchased this power supply for his work and he says he loves it and uses it almost every day. It converts 115 volts ac to 48 volts dc output. It has a rheostat from 12-48 volts output and it works great. He uses it on microwave telecommunications equipment.

Hello,it can works well with DC 11V-DC 13V ,but maybe become very hot More than DC 13V and become short lifetime,so DC 11.5V- DC 12.5V is the best input voltage ,thanks!

to start with u cant "see" a "3 volt ac current". its either 3 volts or some measure of current across a load, ie milliamps. voltage is volts, not current. the fact that its "ac" more than likely means its just electrical noise. Assuming its a relay contact for the output u should be able to use it as a switch no problems. if it still didn't work you would tie it to probably ground using a 4.7k or higher resistor, then use a 1k or less to pull the signal up.

It requires a DC9V-DC12V 250mA. So you have a range of volts to work with, but a set milliamp. Good luck. Have fun.

mine did NOT come with schematic or documentation of any kind. I would NOT expect it to operate a low current relay, the output will only trigger a logic level signal in the very low milliamp range. 0-5vdc

On AC current it is OK but on DC it is very unstable and you have to constantly pushing Reset because after measuring a current it does not returns to zero, it stays at there last measure.

The proper way of wiring this switch and if it needed AC or DC was confusing to me as well. Here's a good picture showing how to wire it with DC: https://www.greenlivingforu.com/sites/default/files/100_2488.JPG

Considering batteries are DC energy...you should be able to make the necessary modifications to the hardware in order to expand on the input methods. Alternating Current(Household outlet); however, would be completely different. Requiring a relay of some kind.

There is no DC amperage rating on the relay. At 120v it is rated 12 Full load amps and 60 Locked rotor amps. At 277v it is rated 6 Full load amps and 35 Locked rotor amps. I am using mine to control a 24v. 40va transformer and it has been working fine since September.

could you please check and tell me what's the rating for the external DC supply ? Vdc ? and current rating (mA)?appreciate your help.thx

The relay enables are DIGITAL, so 5V signals. Can use resistors in line to divide the voltage for 12V activation if desired. The RELAY outputs can carry 10 amps each up to 28VDC or 250VAC.

Yes the output is 12v dc, I use it for my landscape lighting. I also used another for my ikea halogen lighting. Note they are indoor use only. I had them outside in the cold weather and I got flickering when I dimmed them. When I put them inside the flickering stopped. Great product if you need it to dim lighting at 12 volts dc. Worked for me, hope it works for you. Good luck!

The output of this (electronic) transformer is 11.7VAC (AC!), not DC. That being said, most low voltage DC switches will function OK with when used with low voltage AC. "jimyastic" makes a good point about circuit protection, however I would assume if this device conforms to required UL standards (UL approved?) then it's behaviour during use and when it fails has been satisfactorily addressed and shouldn't be of concern.

No, the idea for this one is a booster. The output is variable, but I don't think there's much overlap between its acceptable input voltage and its output. From my unit, it certainly couldn't go as low as a 5 v DC output.

I use this relay on a 12VAC circuit. Works great. I think there is a small diode in series with the coil , so the coil would be DC. Check the one you have it might be the same.
